Jonathan Kim c561dc7183 [svn-r19400] Purpose: 
Fix for Bug1975 h5diff - support recursive comparison on group when specified as an object

Description:
 Compare member objects and groups recursively when two files or groups are specified to be compared. Support parallel diff and handling symbolic links accordingly.
